CHANGE-MAKING MACHINE.

Application file iMay 18, 1915.

To all whom it may concern:

a citizen of the United States, and 'a resident of Frechold,.in the county of Monmouth and State of New Jersey, have invented a new and Improved Change-h laking Machine, of which the following is a full, clear, and exact description.

My invention relates to'change making machines, and has. reference more particularly to an electrically operated machine whereby thedelivery mechanism and the controlling mechanism can be located at any difi'erent suitable places.

The object of the invention is to provide a simple, strong, efficient and inexpensive change making machine wherebyany change Within one dollar can be easily and quickly delivered by the displacement of a proper utton associated with a selector.

With the above and other objects in view, the nature of which will more fully appear as the description proceeds, the invention consists. in the novel construction, combination and arrangement of parts as herein fully described, illustrated and claimed. In the accompanying drawings, forming part of the application, similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a horizontal section on line 1-1, Fig. 2, illustrating 'my change making machine; Fig. 2 is a vertical section-on line of the keyboard on line 3- a Fig. i; Fig. 4: is a cross section on line 4-4, Fig. 3; Fig. 5 is a. section on line 5-." Fig. 3, showing only the details of the contact bar; Fig. 6 .is a section through a coin receptacle showing the details thereof; and Fig.7 is'a diagram of the electrical control of the apparatus.

Referring to the drawings, 8 represents the frame or casing of the change making machine, which has, preferably. an inclined front 9, making the casing narrower at the top than at the bottom. The front 9 of the casing is provided with semi-cylindrical re- 4 cesses 10, each having a bottom 11 partly projecting out of the front 9. These semicylindrical recesses 10 form coin receptacles in the frame. The said receptacles can be made independent of the casing, and set into the front. If desired all of the coin receptacles formed by the semi-cylindrical recesses 10 can be provided with a coverf Eachotthecoin-receptacles has a slot 12 in the Specification of Letters Patent.

bottom thereof directed from the rear to the front of the coin receptacle. Lips 13 are formed in the front of the coin receptacle, at the bottom, which are intended to oncompass the lowermost coins within the rec ptacle and lock their movement toward the front. The lips 130i each coin receptacle have undercut grooves 14 above the bottom 11. These grooves 14 are substantially equal to the thickness of a coin or coins for which the coin receptacle is intended. so that a coin or two placed on the bottom 11 registers with the grooves 14.

A push-bar. 15 is provided for each coin receptacle, and it engages with one of its:

ends the rear end of the corresponding slot 12. The other end of the bar 15 is pivotally connected to an arm 16 which ismounted to oscillate within the casing. It will be noted that each push-bar is disposed inoperatively to the outlet of the coin receptacle, and to bring the same into operative relation with the outlet ot'the coin receptacle, a notch 17 is provided in the back of the receptacle in plane with the grooves 14, which form the outlet of the coin receptacle. end of the push bar into the notch 17, that is, into plane with 18 is provided above each bar. Said magnets are preferably secured to the hack of.

the coin receptacles.

the grooves 14, a magnet To bring the All of the arms 16 associated with the push-bars engaging the coin receptacles containing the five, ten, twenty-five and fifty cent pieces are connected to a key-rocking shaft 19. The arms associated with the push-bars 15, which engage the one-cent receptacles, are connected to another rocking shaft 20. The two shafts are preferably in alincment,- and each has a rigid arm 21, the end of which arm loosely engages a solenoid core 22 tain magnets 18 are energized, in which case It will be noted that whenever the unless ceror an extension thereof. The," core 22 is normally maintained out of the,

the push bar will be brought in a plane with the lowermost coin. and, the same can be forced through the grooves 14 out of the receptacle. v

My change machin in its smallest form,

will contain three one-cent receptacles A,

one five-cent receptacle B, two ten-cent re-- noid coil 23 which operates the push-barsof the one-cent receptacles. The keyboard of the other receptacles contains contact bars 27, disposed-parallelly, each connected to a corresponding magnet 18. A similar contact bar 28 is provided on each side of the series of contact bars 27. The said contact bars 28 are in connection with the solenoid coils 23 which operate the push-bars 15 of the receptacles B to E inclusive.

All of the contact bars 27 are depressible within the frame 29 of the keyboard, resilient members 30 being provided for the contact bars to bring, them to their normal position within the frame 29. Disposed transversely of the contact bars 27 are keys or selectors 31, one end of which key is pivoted within the frame while the other end carries a pivotally connected plunger 32 with which a resilient member 33 is associated, and which normally tends to maintain the key 31 above the contact bar. The alternate keys 31 are pivoted on opposite ends, so that a largernumber of keys can be provided in a small space. The keys 34 controlling the one-cent receptacles are hinged on the same side, and there are three keys.

From the diagram shown in Fig. 7, it will be noted that the engagement of the key 34 with contact bar. or bars 25 takes place before the engagement of the said key with the contact bar 26. Therefore, the corresponding push-bar 15 is brought into operative relation with the lowermost penny or pennies in the receptacle according to which of the bars is depressed. The subsequent engagement of the key with the contact bar 26 causes the rocking of all the arms connected to the rocking shaft 20. As shown in Fig. 7, the key 34: for the numeral 2 is depressed, thus engaging a contact bar 25; therefore the corresponding magnet 18 is energized and the corresponding push-bar brought into plane with the two lowermost pennies. One of the penny receptacles has its grooves 14 equal to the thickness of a penny. The other two receptacles have their grooves 14 equal to the thickness of two pennies.- Therefore, from two receptacles the displacement of the bar will cause a displace- -ment of two pennies. The said lgey 34 also engages the contact bar 26 which causes'the' displacement of the pushbars. Wheh the key 34 having the number 1' on its plunger is depressed, two contact bars 25 will. be engaged by the depression, and, consequently, two push-bars 15 will be placed into operative relation with their corresponding penny receptacles. The subsequent engagement of the key 3 1 with the contact bar' 26 will rock the shaft 20 and cause the lowermost coins to be forced out of the coin receptacles. In the keyboard for the other coins, each key is so arranged that when a key carrying a certain number of units is depressed the proper contact bars 27 are engaged previous to the engagement of the key with the contact bar 28, and, therefore, the corresponding proper coins will be ejected from their receptacles, equal to the number carried by the key. To deliver ninety-five cents, the corresponding key is depressed, causing the engagement with four contact bars in connection with the magnets which control the push-bars associated with the fifty-cent receptacle, twenty-five cent receptacle and the two tencent receptacles respectively. It will also engage a contact bar 28, causing the rocking of all the push-bars; but the other pushbars remain in inoperative position, that is, they are not'brought into plane with the lowermost coins. and, therefore, only those coins will be delivered that have been enupermit the machine to dispense, in addition to the change for twenty-five and fifty cents, twenty-five and fifty-cent coins.

From the ilbOX'B description it will be seen that in my change making machine thecoindelivery member is normally ininoperative position, and the means for actuating said member, which are controlled by the key,

causes the operation of the means which brings the delivery member into operative relation with the coin before the actuating mechanism is'operated. Furthermore, the selection of the proper delivery members is obtained simultaneously with the operatic of the actuating mechanism.

While I have described the principle of operation, together with the device which I now consider to be the best embodiment thereof, I desire to have it understood that i the device shownis merely illustrative and' that such. changes may he made as are within thescope of the appended claims.
